PUMP.

Application Yfiled February 7, 1921.

The primary object orf the invention is to' ]firovide a comparativelysimply constructed, small, compact pumpivhich is capable of ready andeasy assembling and disassembling and Will have a `greater capacity Jforpumping and provide a maximum :pumping action more expeditiously andeconomically than the ordinary pump.

Another object of the invention is to provide ina pump of the characterdescribed, novel`r reliable and efect've means 'for transmitting` therotary motionV from a prime mover to a series of reciprocal pumps7 saidmeans and the `pump being so constructed and `compactly arranged thatmore than the ordinary number lot pumps may be ernployed and operatedeffective-ly, reliably and economically to provide a maximum pumpingaction both as to volume and rate of loiv7 it being also provided bysuch arrangement that ready access may be had to the parts oit the pump'for the purpose ol inspection, repair or renewal of said parts.

'A further object is to `pro-vide a Inovel valve construction and valvearrangement for a pump of the character described whereby little or noroom is taken up by the valves and a savingr in space is provided asWeill 'and a gain in the efficiency oit valvular opeiationand the pump`as a Whole is consummated.

The invention possesses other advantages and'teatures some of which,with the foregoing will be set `ii'o'rt'h at length in the 'followingdescription `Where I shall outline 4in full that 'form ot' the inventionWhich I have selected -or illustration in the drawings accompanying andforming a part of the presentispeciication. In said drawings I-.haveshown one form of the construction of my invention, but it is to Abeunderstood that l do not limit myself to such form since the inventionas expressed in the Specification of Letters Patent.

claims `may be embodied in a plurality ot forms.

Referring to the drawing` the figure represents a vertical sectionalviewof the pump of this invention.

In carrying out the invention there is proyided as shown in theaccompanying dran ing, a pump casingy or housing l having an intakeconnection 2 and an outlet or discharge connection 3, The housingpreferably includes-a base section d which carries the intake connectionQ and is bolted as at 5 to a super-imposed pump cylinder section 6. A.body or intermediate section T is bolted at 8 to the upper sideo'f thecylinder section 6 and carries the outlet or discharge connection 3. Ahead section 9 is boltef as at 10 onto the upper side ot theintermediate or body section 7. A hand hole plate 10 is provided on thebase section 4.- .and is secu-red thereto by bolts 11. Other hand holeplates not shown may be provided as desired.

Extending into the housing' through a bearing l2 in an offset portion 13of the head section 9 is a drive s hattl li which is driven from a motoror other suitable prime mover (not shown). bearing- 15 receives theinner end of this shaft Within the otlset portion. A pinion 16 is keyedupon the sli-artt and meshes with a large spur gear 1T keyed upon anupright main shaft 1S. The shaft 18 isv joufrnalled at its ends inbearings i9 `and 2O provided at opposite central. points of theintermediate and head sections ot the housing` said gear i7 beingdisposed Within Vthe head section.

Associated with and operated by the shaft i6 is means vgenerallydesignated 2i tor transform-ing the rotary movement to ciprocatory`nimfeinent and operating a plurality of independent pump mechanisms 22which latter are carried in the sections (i and 7.

The means 2l comprises a collar 23 loosely surrounding the shaft 16 just beloiv the gear 17. The collar is provided with radially extendingapertured ears Q4. Pivoted as at 2,5 in these ears are substantially Lshaped bell cranks 26.' The collar is connected by spaced Webs 27 withan annular support 28 li-tted nonrotatably but removably in the upperend oiE the housing section 7 and the bell cranks ope 'ate in the slotsor spaces bctween said webs. The lower ends of the bell cranks areslidably engaged with an eccentric member 29 keyed to the shaft 16. Theeccentric comprises a circular disc 30 eccentrically mounted on theshaft and provided on its upper side with an annular groove 31, thegroove being semi-circular in cross section. The lower ends of the bellcranks have reduced screw-threaded extensions 32 which turn into socketsSil formed Vin bca-ring balls 254.. rfhe balls 3l are thus removable andmay be easily replaced when worn. These balls slidably engage in thegroove 8l and are held in place by an annular plate 35 secured byfastenings 36 to the upper side of the disc 30. fit the periphery of theplate 35 is provided an annular upetanding ange l3T having curved ballengaging` face S7. As the eccentric rotates the balls 34 slide in thcgroove and the bell. cranks are rocked. on their pivots.

Links 38 `ioin the upper ends ot pump pis ton rods 39 with the upperends of thc bell cranks and said'i'ods 39 are slidable tliroughlubricating bushings d() carried in the upper wall L.ll of the housingsection T. This wall serves as a fluid tight seal between the sections 7and 8 and confines the fluid being pumped to the section 7 whereby saidfluid will discharge through the outlet connection 3. The bushings l0serve as stuffing boxes. The rods 39 extend into pump cylinders 42arranged in arcuate formation in the scction 6 of the housing. Thecylinders are open at both ends and hollow pump pistons 43 are attachedto the rods 38 and are ieV ciprocally mounted in said cylinders. As manyas nine or twelve, of the cylinders. or better, individual pumps may beprovided, in fact, any number as desired may bc used.

T he hollow pistons are cach provided with a lower end wall tl having anintake port therein. The upper side of each piston is open and providedwith an annular valve seat 1lb' upon which seat an annular upwardlyopening check valve 47 engages so as to control the passage of the fluidthrough the pistons. Check valvesV ld are slidable upon the rods 39 andseat upon the upper ends of the cylinders d2. Springs t9 surround therods 39, abut the valves e8 and bushings 40 so to normally hold thevalves in closed position. Y

A vacuum chamber 50v is provided centrally in the section 6 of thehousing and opens on the lower side of said section into the basesection of the housing. A. bracing stud 51 Vis mounted between and abatsopposed central portions of the sections 6 and of thehousing. VTheintake connection 2 Vincludes a passage 52 which extends first upwardlyand then downwardly so as to provide a trap within the base section 4lof yhe housing, whereby, sufficient liquid is at all times maintained inthe base section Vto eliminate the necessity of priming the pump.

O pera time.

lihen the shaft 18 is rotated the eccentric revolves Vand causes thebell cranks to iock. .ihis reciprocates the rods 39 and pistonsflilattached thereto so as to quickly and reliablyY effect the pumpingaction in cycles in the several pumps. As each piston is drawn upmu-dlyopening check valve 47 opens the valve and the waterV is forced throughthe piston against the valve lSand the pressure will open said valve4.8.' The water then passes .into the suction `and out through theoutlet connection 3. This action takes place in each pump and it will beseen that upon each revolution of the main shaft an effective andthorough pump action is provided. .ln the event that one or'more of thepumps become inoperative the other pumps will function withoutinterference in the normal manner and in this way the serriceahility andreliability of the pump will be greatly increased. i f
